The Optrix HD features a 3-element wide-angle lens that enables a 175-degree view, while a variety of interchangeable mounts enables you to position the phone to how you require. These mounts can also be attached to a bike or helmet, leaving you free to cycle up a mountain or climb a rock face while the anti-vibration technology will help keep your footage steady.

The case has been military tested and has been awarded MIL-STD-810F billing. That is “double hard” to you and me.

The Optrix XD case can be ordered online from both SportHitech and Amazon for $99.99.
